which way to drill EGT

[barry1me]

I have read several different ways to do this.

1) put greese on the drill bit and remove the bit backwards to collect shavings. This method is what is instructed to use from EDGE.

2) do not use greese and use some type of vaccum to collect shavings.

3) drill hole and turn engine on to push out shavings. I have only heard of a few people say to do this.

Im still a little nervous about drilling a hole in my manifold with shavings possibly entering my turbo or worse. Which is the safest way to do this?

I used greese, then vaccumed...............................I feel your pain I sweated bullets the first 500 mi. after installing the prob, but that was 65000mi ago, just take your time and you will be fine!

I would personally prefer to drill it dry, use a shop vac and then also poke a small magnet around inside the hole. If you use grease, it may contain all the shavings, but if it doesn't they will be stuck to grease and have much less of chance being extracted.

Gravity is working with you and 99% of the shavings should fall down and out. A good strong shop vac should also suck out anything that gets left behind.

I have heard horror stories about a lot of things, but I don't recall hearing from anybody first hand that they lost a turbo from installing a pyro. I hear rumors of a friend of a friend of a cousin, but nothing from the horse's mouth.

Has anyone tried welding a nut to the exhaust ???
I am getting ready to install guages and thought this might be a option.

i dont think youll get a true reading since its not contacting the exhaust gasses

I think you would have a tough time welding to cast steel. Im assuming ford didnt use a cast that has easy weldibility when designing there manifolds

bring it over and we will do it at my house. Being I done them before with no problems. I have everything needed to do the job ok.

drill a SMALL pilot hole and then drill with the desired size, then tap it. I've done several and never had any problems. Once you start drilling you'll see how MINUTE the particles are and will no longer worry about them affecting the turbo. Besides they'll only affect the exhaust side which doesn't matter as much as the other side.

I appreciate your generosity. You are one of the most generous people to lend a hand that I think I have ever met on a forum I have about an hour or so to mess around with this tonight after work and I figured I would do it. I have the tap I need and drill bits so it shouldnt be that hard, Im just curious to how people did procedure.

on a side note why I dont have time to tinker with the F250:
Im hoping to finish up the jeep tonight. Last night I got the alloy chomoly axle shafts done in the rear, front axle shafts removed, and the carrier out. Tonight I have to install the locker up front, alloy axle shafts up front, finish the exhaust, and adjust the line pressure on the trans. If time prevails I will install rear bumper and coil spring spacers up front.....its like the song that never ends with jeeps
